Mustafa Iman created HIVE-23746: ----------------------------------- Summary: Send task attempts async from AM to daemons Key: HIVE-23746 URL: https://issues.apache.org/jira/browse/HIVE-23746 Project: Hive Issue Type: Sub-task Components: llap Reporter: Mustafa Iman Assignee: Mustafa Iman
LlapTaskCommunicator uses sync client to send task attempts. There are fixed number of communication threads (10 by default). This causes unneccessary delays when there are enough free execution slots in daemons but they do not receive all the tasks because of this bottleneck. LlapTaskCommunicator can use an async client to pass these tasks to daemons. -- This message was sent by Atlassian Jira (v8.3.4#803005)
